    Tidal Wetland Restoration in the Bay-Delta Region: Developing Tools to Measure Carbon Sequestration, Subsidence Reversal, and Climate Resiliance 2021

    Lead California State University [CSU]
    Description Tidal marshes are important ecosystems in the San Francisco-Bay Delta. They remove carbon from the atmosphere, build up soils that buffer our communities from sea level rise, mitigate excessive nutrients (like nitrogen), and provide critical habitat and food resources for a diversity of species. It is difficult to predict how tidal marshes change naturally over time versus as a response to climate change, restoration and water quality changes. This project provides the first ever multi-year dataset of the complete carbon budget of a tidal marsh. This dataset will be used to predict seasonal and annual carbon budgets in tidal marshes over a range of salinities. The model will assess the sustainability of existing and potential restored tidal wetland benefits over the next 100 years using remote sensing data. The model will be an open-source tool designed for use by wetland managers and decision makers in the Bay-Delta region. This project supports ongoing initiatives to restore tidal wetlands in the Delta and our ability to manage them in a changing world.

    California Cooperative Snow Surveys [CCSS] program

    Lead California Department of Water Resource [DWR]
    Description Established in 1929 by the California Legislature, the California Cooperative Snow Surveys (CCSS) program is a partnership of more than 50 state, federal, and private agencies. The cooperating agencies not only share a pool of expert staff but share in funding the program, which collects, analyzes and disseminates snow data from more than 265 snow courses and 130 snow sensors located throughout the Sierra Nevada and Shasta-Trinity mountains. California is the only western state to perform this function on its own. In the other western states, snow surveys are done by the federally funded Natural Resources Conservation Service, which began its program in the mid-1930s. Both programs are similar, and there is a high degree of cooperation between the two entities. DWR is the lead agency in coordinating the CCSS program, which includes: -Maintaining snow surveying and sampling equipment -Training for our partner agencies -Course measurement schedules and data collection -Fiscal and staff resource needs for the various partners within the program. While monitoring doesn't occur in the Delta, snowmelt estimates are used to develop streamflow forecasts for the Sacramento and San Joaquin Rivers that flow through the Delta.

    Coastal Wetland Restoration a Nature Based Decarbonization Multi-Benefit Climate Mitigation Solution: Policy and Governance

    Lead University of California - Davis [UC Davis]
    Description A team at UC Davis (Dr. Mark Lubell, Dr. Gwen Arnold, PhD Candidate Kyra Gmoser-Daskalakis) is conducting social science research on wetland restoration in the California Bay-Delta as part of a larger, interdisciplinary project on wetland restoration across multiple University of California campuses and national labs ("Coastal Wetland Restoration a Nature Based Decarbonization Multi-Benefit Climate Mitigation Solution"). First, the project is conducting social network and spatial analysis using the EcoAtlas project database to examine drivers of wetland restoration investment in the Bay-Delta from the 1980s to now. Second, case studies of individual restoration projects and interviews with 40+ restoration project partners examines barriers to the restoration implementation and perceptions and goals of multi-benefits among interested parties. Preliminary results have been shared at the State of the Estuary and Bay-Delta Science Conferences in 2024. See https://wetlands.ucsc.edu/index.html for more information.
